Uh ... no. YOU need to learn the TRUE history ... your people weren't here first either.
They are truly pawns in a grand game. But then again, so are we, probably.
Hood point. “Mexico” claimed everything that wa Spanish after the Spanish left as part of the “Mexican Empire” (I thought they hated imperialism?).
It began falling apart pretty quickly, first with Panama and Costa Rica gaining independence and shortly after Texas. Eventually even Guatamala left. They were lucky to hold on to Sonora, let alone Arizona and New Mexico.
If you really want to stump a Mexican just ask them which country first invaded Texas with federal troops. They are masters of revisionist history, but they can’t hide the truth.
